Measurement of deformation in rolling and sliding contacts

In this work, mechanisms behind micro-scale changes on the surfaces in
rolling and sliding contacts are studied both experimentally and
numerically. For the experimental study a wear and deformation
measurement system is designed and produced. This system is composed of
an interference microscope, a controllable rotating table and a friction
device. The system allows measurement of the micro and nano-scale local
changes on the surface micro-geometry during a wear or deformation
experiment.
